Product overview
Capabilities, pricing and fit
Bolna is an open-source orchestration framework plus a managed API and dashboard for building conversational voice agents. The framework connects telephony, speech recognition, language models, speech synthesis, streaming, and post-call tools; it is voice-agent infrastructure rather than a finished receptionist or single autonomous worker.
Information as of August 30, 2026
What it can do
- Pluggable voice orchestration
Bolna streams conversations across telephony, speech recognition, LLM, and speech-synthesis providers through configurable agent pipelines.[1]
- Agent management API
The REST interface supports creating, reading, editing, listing, and deleting agents with JSON-defined prompts, tasks, providers, and call behavior.[2]
- Hosted and MCP access
Bolna also provides a managed API/dashboard and an official remote MCP server for managing agents, calls, phone numbers, and related platform operations from compatible clients.[1], [3]
Where it fits best
- Developers building customizable inbound or outbound voice agents who want an MIT-licensed orchestration layer with pluggable telephony, ASR, LLM, and TTS providers.[1]
Pricing and availability
The core Bolna repository is MIT-licensed and free to self-host. Users pay their chosen telephony, speech, model, voice, hosting, and networking providers; the checked official pages do not publish a current managed-service rate card.[1]
Platforms: Python framework, REST API, No-code web dashboard, Remote MCP server, Telephony and web-call integrations[1], [2], [3]
Access: Self-hosted with Docker, Bolna-managed APIs and dashboard, Embedded in customer voice applications[1], [2], [3]
Important considerations
- The repository is the open-source orchestration layer, while the hosted APIs and no-code dashboard are separate closed-source components.[1]
- A basic self-hosted phone setup requires Docker plus telephony, speech, model, voice, tunnel, and persistence configuration, along with the relevant provider accounts and credentials.[1]
- The public repository says maintainership has fluctuated and is actively seeking maintainers, which teams should consider when depending on the community framework.[1]
